China Southern Power Grid Micro-Friendship

Can China decarbonize the southern power grid by 2060?

Decarbonization of the Southern Power Grid in China is feasible by 2060 but requires converting a large cropland area to support solar and wind energy; expansion of hydropower will impact the transboundary rivers according to a power system optimization model set up for 2020–2060.

Who operates the power grid in Southwest China?

In Southwest China, the China Southern Power Grid company operates the power grid, investment, construction, and dispatching, and the provincial gas companies are responsible for the operation and dispatching of the gas distribution network.

How does distributed energy work in Southwest China?

Therefore, in Southwest China, the combination of distributed energy with traditional power, energy conversion devices, and flexible loads to form MEGs, and the joint operation with the active DN effectively satisfies the overall objectives of power grid operation.

Why are power grid dispatchers facing a security problem in Southwest China?

The rapid growth of distributed photovoltaic and wind power installed capacity in Southwest China has reduced the operation safety margin of the power grid. Power grid dispatchers face the dilemma of ensuring security of the power grid and the output curtailment of renewable energy.

What is a microgrid in China?

In 2004, China began to carry out research on the concept of microgrids as proposed by the United States. This research has been based on the connection of distributed generation to large electrical grids via AC (alternating current) microgrids and the impacts of microgrids on large grids.

What is the future development direction of microgrids in China?

The future development direction of microgrids in China will therefore be towards an energy system that integrates electricity, gas, water, and heat resources, achieves mutual coupling, and solves the problems of efficient energy utilization and peak regulation .
